NON-REFlLLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent No. 584,455, dated June 15, 1897. Application filed september 12,1896. Serial No. 605,667. (No model.)

To all whom 2113' may concern.-

Be it known that I, JOHN BOSTON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Non-Refillable Bottles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a novel construction in what I term a non-refillable bottle; and it consists in the features of construction hereinafter described and claimed.

In the accompanying drawings, illustrating this invention, Figure 1 is a central vertical section of a bottle constructed in accordance with this invention. Fig. 2 is a similar section showing the position of the parts when the bottle is inverted. Fig. 3 is a cross-section on line 3 3 of Fig. 1. Fig. 4. is a crosssection on the line L 4 of Fig. 1.

Referring to said drawings, 1 indicates the neck of the bottle, which is provided inte: riorly with two valve-seats 2 and 3. These valve-seats are secured within the neck of the bottle in the following manner: At the point whereat it is desired to fasten these valve seats the interior of the neck is provided with a groove 4, and an opening 5 is made through the neck communicating with this groove. The valve-seats are provided exteriorly with grooves 6 to correspond with the groove in the neck of the bottle. hen these valveseats are put in place, their grooves 6 stand opposite the groove 4 of the neck, and a suitable cement is poured through the opening 5, which passes around the channels formed by the groove 4, and thus effectually seals the valve-seats in place. The cement employed for this purpose is preferably a solution of sodium silicate and ground glass. This solution is used because it withstands all corrosive effects after drying.

The lower valve-seat 2 is provided with a cylindrical central portion 7 and outwardlyfiaring end portions 8. Situated within this valve-seat is a valve 9, having flaring end portions to fit the flaring end portions of the valve seat, and a cylindrical portion smaller than the cylindrical portion of the valve-seat, but longer. In this way the valve has a slight longitudinal play within the valve-seat. The lower end portion of the valve is provided with longitudinal grooves 10, extending from the lower end thereof to about the junction of the cylindrical portion and the upper flaring portion. The upper end portion of the valve 9 is provided with a plurality of grooves 11.

The valve-seat 3, which is situated above the valve-seat 2, consists of a ring provided on its lower face with the lugs 12, and within the valve-seat 2 is situated a valve 13, having a central portion or stem of less diameter than the opening in the ring 3, butlonger than same, and provided above and below the ring or valve-seat with disks let and 15. The upper disk let is provided with a series of marginal grooves 17, while the lower disk 15 is plain and smaller than the neck of the bottle, while the upper disk lat fits nicely within the neck of the bottle.

In use the bottle is filled in the ordinary way, after which valve 9 and valveseat 2 are introduced and sealed in the manner described. The valve 13 and valve-seat 3 are then introduced and sealed. A11 ordinary cork is then placed in the mouth of the bottle, and when it is desired to. empty the contents this cork is extracted in the usual manner, and by inverting the bottle the valves 9 and 13 both fall toward the mouth of the bottle, as shown in Fig. 2, permittingthe liquid to pass through the grooves 11 in the end of the valve 9, then around the edges of the disk 15, between the stem or valve 13 and to its seat 3, and then through the groove 17 and disk 14. It is obvious, however, that this bottle cannot be refilled without breaking the parts or by extracting the filling in the grooves 4 and 6, and this latter expedient is hardly possible, owing to the shape of the grooves. Further, the bottle cannot be refilled by sub- Inersion, shaking, or forcing the liquid therein, for whenever it stands in an upright position the valves 9 and 13 instantly close down upon the top portions of the valve -seats, thereby sealing the same.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A bottle having a valve-seat secured within the neck thereof, said valve-seat having a central cylindrical portion and outwardly-flaring end portions, a valve situated within said valve-seat and having a central cylindrical portion smaller than the central cylindrical portion of the valve-seat but longer than the same, and having outwardly-flaring end portions, grooves in the cylindrical and lower end portion of said valve, grooves or notches in thenpper end of said valve, and an outwardly opening valve between said first-mentioned valve and the mouth of the bottle.

2. A bottle having a ring-shaped valve-seat in the neck thereof and provided with lugs on its lower face, a valve situated within said valve-seat and consisting of a stem longer but ofless diameter than the openingthrongh the LOUIS G. SoHUMAcHnR, MAGGIE A. HORN.
